Known Problems and Limitations

Release 11.1.1
Work-around
: To correct this problem and enable ICR partitions to be created
correctly, make sure that you add the ICR partition configuration before the
subscriber interface configuration in the .scr file. You can perform this reordering by
modifying the .scr file to place the commands that configure subinterfaces for ICR
partitions before the commands used for VLAN-based or S-VLAN-based grouping of
subscribers.
z
When you configure ICR settings using a CLI macro, ICR commands are run in quick
succession. Sometimes, in such a scenario, the active SRP module resets if the event
that causes the change of state of the VRRP instance reaches the ICR application
before the ICR partition has been created. [Defect ID 184095]
Work-around
: To avoid this problem, add an additional delay of one second using
the
sleep
command in the macro, before the
ip vrrp vrid enable
command that is
written in the macro to enable VRRP instance.
For example, consider a macro that contains the following commands:
ip vrrp
vrid
enable
ip vrrp
vrid
icr-partition
partitionId
Modify the macro, as follows, to add a delay of one second before the VRRP instance
ID is enabled on the router and a delay of another second before the ICR partition
that corresponds to the VRRP instance is created:
sleep 1
ip vrrp
vrid
enable
sleep
1
ip vrrp
vrid
icr-partition
partitionId
IGMP
z
IGMPv3 proxy is not supported. [Defect ID 46038]
z
The E Series router IGMPv3 proxy does not operate correctly in the presence of
IGMPv2 queriers. [Defect ID 46039/46045]
Work-around
: If an IGMPv2 router is present on the network, do not configure version
3 with the
ip igmp-proxy version
command on that network interface. (Version 2 is
the default.)
z
The default value for the IGMPv3 proxy unsolicited report interval timer should be 1
second rather than 10 seconds (the value for v2). [Defect ID 46040]
z
When more than about 100,000 mapped OIF entries are configured on a virtual
router, issuing the
no virtual router
command for this and other virtual routers does
not delete all the virtual routers within the deletion timeout interval (3 minutes). The
virtual routers do eventually delete after this timeout. [Defect ID 63882]
z
The E Series router does not log a warning when it receives an IGMPv2 query but is
not configured to use IGMPv2 on the interface. [Defect ID 46046]
IP
z
The ES2 4G LM can reset during a unified ISSU after you issue the issu start
command on a router configured with 8000 dynamic VCs and 8000
packet-triggered dynamic subscriber interfaces. [Defect ID 86761]
